Patent number: 8345860Abstract: A method, a system and a computer program product for fast detection of the onset of a near-end signal is provided. An Acoustic Echo Canceller (AEC) attenuates an acoustic echo present in a tele-communication network. The AEC includes an adaptive filter that estimates the acoustic echo and generates an error signal. The error signal is the difference between the acoustic echo and the estimate of acoustic echo plus a near-end signal, if present. The method comprises computing an onset indicator parameter from the error signal and the estimate of acoustic echo. Several other parameters are subsequently calculated by using the onset indicator parameter, the error signal and the estimate of acoustic echo. The presence of the near-end signal is detected with very low detection delay by using the parameters mentioned above and one or more threshold values.Type: GrantFiled: May 9, 2008Date of Patent: January 1, 2013Assignee: Hellosoft India Pvt.

Patent number: 8258876Abstract: A protection circuit for a power amplifier connected as a negative feedback loop around the power amplifier. The negative feedback loop comprises a detector circuit, a driver circuit and an attenuator circuit. The detector circuit receives output voltage from the power amplifier and generates a signal when the output voltage exceeds a predefined threshold. The driver circuit filters the signal received from the detector circuit to maintain feedback loop stability and adjusts the feedback loop bandwidth and gain to provide a filtered signal. The attenuator circuit receives the filtered signal and attenuates the input voltage of the power amplifier to reduce the output voltage of the power amplifier to a level below the predefined threshold.Type: GrantFiled: January 7, 2011Date of Patent: September 4, 2012Assignee: Anadigics, Inc.Inventors: David Osika, Joel Lott, Julio Reyes

Patent number: 8009773Abstract: A method and system for low-complexity implementation of a Viterbi Decoder with near optimal performance has been disclosed. The Viterbi decoding technique is diagrammatically represented as a trellis. The trellis includes various states at different time instants, and branches connecting these states. Each state has an associated state metric and a survivor path sequence, whereas each branch has a branch metric. The state metric for each current state is checked for crossing a predefined limit. If it crosses the predefined limit, the state metric is updated with a new metric that is obtained by subtracting a constant value from the state metric. Thereafter, the method finds a common path in the trellis at each state and updates the survivor path sequence of each state. The Most Significant Bits (MSBs) of the survivor path sequences of the states at a particular time instant are computed and the original data is decoded, based on the count of ‘0s’ and ‘1s’ in the MSBs.Type: GrantFiled: April 4, 2008Date of Patent: August 30, 2011Assignee: Hellosoft India Pvt.

Patent number: 7985295Abstract: An RF heating system for a substrate or substrates including a susceptor for supporting the substrate; one or more RF heating coils; and a platen disposed between the RF heating coil and the substrate. The platen is constructed of materials that become heated under RF energy, which will then radiate heat into the susceptor and the substrate. In this way the susceptor need not be constructed of materials that become heated under RF energy thus minimizing levitation. The platen provides a uniform temperature profile across the substrates, benefiting from a more diffused heat source. The RF heating system may also be utilized in CVD apparatus that deposits materials on a continuous tape or roll.Type: GrantFiled: March 12, 2007Date of Patent: July 26, 2011Assignee: Structured Materials Inc.Inventor: Gary S.
